Hi, you have the original Sony CD Player from 1983. I got the 2 best guys to fix it. First, Stan Warren. Stan is one of the best modifiers for digital and fixes everything. He used to be the main designer at PS Audio. He's in Portland Oregon. His number is 541 344 3696. The other guy I would recommend, is Terry Dewich. Terry was one of the main designers for Phillips in the 80s. He fixes everything. Tube Amps from the 60s to now. Krell, levinson, all those big receivers from the 70s. He is one of the most knowledgable people when it comes to fixing audio. Here's his email address. Terry@mcintoshaudio.com
